HiThanks
for using FixYa. You’ll need to reset the Projection TV and to reset it follow
these steps:

Turn off the television and
wait for 5 minutes.

2. After 5 minutes unplug the television power cord from the electrical outlet.
3. Let the television remain without power for more then 1 minute.
4. Plug the power cord back into the electrical outlet. If the television is
plugged into a power surge protector, remove it from there and plug it directly
into the wall outlet. Turn on the television. If the issue is resolved, then
the problem is with the power surge protector and not the television.If the issue is not resolved then this might
have happened due to over-voltage. Please check the power supply unit for
swollen/bulged capacitors and burnt wires/components on the power supply board
of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and
unplug the TV for at least 1 hour (this will drain off current from
all components especially capacitors) before you perform any repairs. Also note
that the TV consists of very high voltages even when it is in OFF condition.
All this is only recommended if you have electrical expertise and know how to
solder/re-solder components.
Please do accept the solution if the issue is resolved or else revert for
further assistance.

Sounds like bad capacitors on the deflection board CP150, CP120 and CP114 specifically as they are famous for failing when you unplug the power cord because they drain and then when the power is plugged back in they cant recharge and the set will not turn off. You can get the repair kit called the CP150 , CP120 Cp114 repair kit at the folloeing link kust scroll down the page it contains instructions its very inexpensive http://tvrepairworld.com/rca_repair_kits

Hi, i think the problem is the back light(of the panel) and if it's dead then you're done with the TV. There is 10% chance that it could have happend. This set uses two inverter boards. Check the supply 3.3V and 12V to the D board. The inverter boards need to be checked and most possibly require replacement. The inverter is the power supply for backlight just like a ballast is for a lamp in DLP TVs. LG LCDs use good inverters and back light in comparison to Samsung. Usually a bad transformer in the board causes this to happen. I wish I had some easy fix. Fixing it would cost you around $150(DIY).

I had the same sympton on my tv...it worked fine one day and the next day it would flash a green light a few times you would see the screen power on, but still be dark then the power light would go red. I couldn't do anything on the tv no menus or sound. It turned out to be a bad power supply, a new power supply will run around $200-300 - in my opinion it wasn't worth fixing. My neighbor was able to fix my tv - he repairs electronics - ended up cost me $100.00 - its been running for 7 months now no problems so far...I can have him fix this for you if you are in the area - shipping makes this to expensive..he is located in south jersey...or you can try a tv repair shop ( i called for this but they wanted between $75-100 to just look at the unit + repair cost - i would of been back to the 200-300 range) let me know if you need help...Johnnetplus@comcast.net
